During the reunion, Adriana De Moura accuses Joanna Krupa of breaking up Yolanda Foster's marriage to Mohamed Hadid. Adriana and Alexia Echevarria both confirm that Brandi told them Joanna slept with Mohamed while he was married to Yolanda, and that Brandi snubbed Joanna at a party recently because of this.

As luck would have it, Brandi was on Watch What Happens Live after the reunion aired and was able to address the rumors.

"Joanna had sex with Mohamed," Brandi tells host Andy Cohen in no uncertain terms. However, it wasn't the only reason Yolanda left him. "It was one of many affairs. It's not the exact situation. But Mohamed and Yolanda are great now."

Brandi also explains why she snubbed Joanna at that party. "It's just that, when Yolanda and I were at a party, and Joanna started to walk up to us, we had to go," she says.

As you can imagine, Joanna did not take kindly to Brandi saying this. While WWHL was airing, Joanna took to Twitter to slam Brandi, writing, "No wonder her husband left her." Yikes.

When Andy told Brandi about this, Brandi took things one step further. "Well, Mohamed did tell me that her p—sy smelled, Brandi says. "I'm not lying — and Lisa Vanderpump was there when he said it. Sorry, bitch— I win."

Wow! We had no idea that either Brandi or Joanna would be willing to sink so low about each other. It should also be said that Joanna was spotted hanging out with Lisa Vanderpump last month, and Lisa and Brandi are not on good terms at the moment.

So do you believe Joanna that she and Mohamed were just friends, or do you think she slept with him?
